I'm writing a chrome extension that currently creates an instance of an object when an overlay is loaded. This currently means that a new instance is created for every window that contains the overlay.
I would prefer to be able to create a single instance of the object when the Mozilla starts, and make reference to this instance when other windows are created. This also means that I would like to keep the instance alive after the overlay that created it has been destroyed.
This should just be a simple Singleton model. Is there some type of
registry I can use to store and retrieve a reference to this object
each time the overlay loads, and does anyone have any examples of a
similar implementation? Thanks you,
You want to write an XPCOM component in JS, and call it via XPConnect. Many examples exist. See http://lxr.mozilla.org/mozilla/source/xpcom/sample/nsSample.js, http://lxr.mozilla.org/mozilla/source/toolkit/mozapps/update/src/nsBackgroundUpdateService.js, http://lxr.mozilla.org/mozilla/source/toolkit/mozapps/extensions/src/nsExtensionManager.js.in, and others (http://lxr.mozilla.org/mozilla/search?string=createInstance%3A).
So the better newsgroup, I think, is m.xpcom. Cross-posting with followup-to: set.
